[Please move to logstash forum; sorry]
[https://www.elastic.co/guide/en/logstash/2.0/breaking-changes.html#\_configuration\_changes](https://www.elastic.co/guide/en/logstash/2.0/breaking-changes.html#_configuration_changes)
says:
The Elasticsearch output plugin configuration has the following changes:
[...]
New options: bind\_host, bind\_port, cluster, embedded, embedded\_http\_port, port, sniffing\_delay
This doesn't make sense, since 'cluster' was an option before, not sure why it's listed as a new option, especially since I get this error with logstash 2.0.0:
/opt/logstash/bin/logstash --configtest -f /etc/logstash/conf.d/99\_output.conf
Unknown setting 'cluster' for elasticsearch {:level=\>:error}
In my config, I am using the http elasticsearch transport with:
````auto
elasticsearch {
cluster => "logs"
hosts => ["foo:9200"]```
In any event, is there a supported way to configure what cluster to talk to, or is there simply only one possible cluster when using HTTP?
I don't see the options listed as "new" (except for sniffing_delay) above at:
https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html
so is it possible that they meant "obsolete" rather than "new"?

Indeed, that's incorrect. `embedded` and `embedded_port` were also removed so the list appears to be a mix of additions and deletions.
> In any event, is there a supported way to configure what cluster to talk to, or is there simply only one possible cluster when using HTTP?
The latter. The host:port tuple you supply identifies the cluster. The HTTP API has no cluster parameter.

I've the same problem.
